Use computers to perform system/network operations. Interpret BIT/BITE and error codes to correct system faults. Installs, operates, perform strapping, restrapping, PMCS, and unit level maintenance on COMSEC devices. Operates and performs preventive maintenance checks and services (PMCS) on assigned vehicles. Installs, operates, and performs PMCS on power generators.

MOSC 25F2O. Supervises, and performs as senior team member, in the installation, operation, employment, and direct support systems maintenance of large and small electronic switches and associated equipment. Performs and assists subordinate operators in the conduct of switching and COMSEC operations, Combat Net Radio Interface (CNRI) procedures, and associated computer related technical tasks. Interprets orders and compiles system statistics for the Shift or Node. Request logistical support for switching teams, or shifts. Implements network control center generated changes to support operational requirements. Assist in the conduct of preventive maintenance checks and services (PMCS) procedures on assigned vehicles and power generators.

MOSC 25F30. Supervises and performs complex and multifaceted switching operations functions. Supervise the installation, operation, deployment, provisioning, and maintenance of electronic switching assemblages or systems. Disseminates network orders, compiles operational statistics and reports, and processes requests for logistic support. Coordinates, integrates, and controls the operation of large and small electronic node switches with associated transmission systems and local network subscribers. Performs systems control center operations for the planning, configuration, and employment of switching equipment. Ensures contingency operations plans and routing subsystems are correctly maintained in the database to reflect current operational scenario. Troubleshoots complex system faults and supervises or corrects failures to meet system availability and reliability standards. Interpret operations orders affecting switching operations. Conduct switching technical, operational, and maintenance training of subordinates. Submits consolidated logistic and system status reports.

Other Requirements for Award of MOS 25F:

(1) Normal color vision.

(2) Ability to read, comprehend and clearly enunciate English.

(3) Ability to work for extended periods in a confined area.

(4) Formal Training (completion of MOS 25F Course conducted under the auspices of the USA Signal School) mandatory or meet the ACASP criteria per paragraph (a) and (b) below. Waiver may be granted by Commandant, U.S. Army Signal School, ATTN: ATZH POE, Ft Gordon, GA 30905-5300.
(a) Be eligible for SECRET security access under provisions of AR 380-67.
(b) Must have completed a minimum of 1 year of accredited college or technical school studies in electronics/electronic switching systems repair and WAN network or have 2 years verifiable experience or combination of formal training, experience and certification totaling 2 years, in installing, operating and maintaining telephone exchange or primary branch exchange systems. This experience base should include knowledge of data packet based switching systems equipment and proficiency at the configuration, operation and troubleshooting of routers and E-switches. Having a working knowledge of Network Operation Center (NOC) operations is not mandatory but an added plus.
